Isolated yields are reported of salt mixtures are reported.

Ratios were calculated from crude¹H or³¹P NMR spectra. Ratios of isolated products can differ from the crude reaction mixture.

iso refers to an unidentified phosphonium salt isomer.

Yields calculated by¹H NMR using 1,3,5-trimethoxybenzene as an internal standard.
